Omarchy treats AI coding agents as first-class citizens, but it doesn’t pick a favorite for you. Instead, every major coding-agent CLI comes pre-wired as a lazy-loaded launcher. The launchers are tiny mise-managed stubs in ~/.local/bin/, so nothing is downloaded until the first time you actually run one. Invoke any of these and authenticate when prompted:

Command	Agent
claude	Claude Code
codex	OpenAI Codex
opencode	OpenCode
agy	Google Antigravity CLI
copilot	GitHub Copilot CLI
crush	Crush
grok	Grok CLI from xAI
pi	Mario Zechner’s Pi
omp	Oh My Pi
ori	Ori, OpenRouter’s harness
hermes	Hermes, Nous Research’s agent
muse	Muse Code, Meta’s coding agent
cursor-agent	Cursor CLI

ori is the odd one out: it runs the other harnesses against OpenRouter’s whole model catalog, so ori claude, ori codex, or ori opencode start those agents on whichever model you point them at, and ori code is Ori’s own agent.

To wrap an additional CLI the same way, run omarchy-mise-install <package> [command-name]. The stubs are kept current along with everything else mise manages when you run omarchy update (or the mup alias).

The default agent

Pick your default agent with omarchy default agent <name> or under Setup > Defaults > Agent in the Omarchy Menu (Super + Space). If the agent isn’t installed yet, picking it installs it first. A fresh Omarchy will invite you to make this choice with a one-time notification.

Muse Code — Meta’s muse — uses a preinstalled mise stub like the other agents. Picking it as the default installs Meta’s official launcher through mise’s HTTP backend. The launcher verifies and updates the native binary for your machine.

Once you’ve chosen, Super + Shift + Ctrl + A launches the default agent in a dedicated terminal window (or brings up the picker if you haven’t chosen yet). You can also launch it straight into a task with omarchy agent prompt "Review this project". Agents launched this way run unattended in their respective don’t-stop-to-ask modes, so be ready for them to actually do things! And since agents refuse to remember trust for your home directory, launches from $HOME start in ~/Work instead.

There are terminal shortcuts too: a runs the default agent inline in the current terminal, while c, cx, and cy start OpenCode, Claude Code, and Codex directly (again in their auto-approving modes). Theme changes sync to the agents as well: Claude Code, Pi, OpenCode, and Hermes (once Hermes Desktop is installed) all follow along when you switch the Omarchy theme.

The agents panel

The top bar grows an agents icon the first time Omarchy finds AI coding usage on the machine (and stays out of the way until then). The panel behind it tracks every subscription in one place: your plan, the percentage used of the 5-hour session and weekly limits (or the remaining prepaid balance), and token usage by day and by model. Claude Code, Codex, and Fireworks are covered out of the box.

Left-click the bar icon for the panel, right-click to launch your default agent. The usage records behind it are regenerated every 15 minutes by omarchy agent usage-update, and the panel can even merge usage from your other machines via a synced folder. See the README under $OMARCHY_PATH/shell/plugins/agents/ for the full settings.

Crash diagnosis

Omarchy watches systemd-coredump for process crashes. When something segfaults, you’ll get a “Process crashed” notification — click it, and the crash is handed to your default agent along with Omarchy’s diagnose-crash skill, which walks the agent through establishing the facts from the core dump and deciding whether the crash is worth reporting upstream. You can also run it by hand against any PID from coredumpctl list with omarchy agent crash <pid>.

The watching is on by default. Turn it off under Trigger > Toggle > Crash Capture (or with omarchy toggle crash-capture) and the notifications stop; omarchy agent crash <pid> still works by hand.

Crashes can also be silenced one program at a time, which is what the diagnosis offers you at the end. omarchy crash mute hyprland stops the notifications for that program only, omarchy crash mute hyprland off brings them back, and omarchy crash mute on its own lists what you’ve muted. It takes the binary’s path as happily as its name, so omarchy crash mute /usr/bin/hyprland does the same thing. Quote a name with a space in it, as in omarchy crash mute 'Some App'. Everything else still notifies, and the muted program still crashes — this hides the reminder, it doesn’t fix anything.

Desktop apps

The Install > AI menu also carries a few graphical AI apps: the ChatGPT desktop app, the Claude desktop app (Anthropic’s Linux beta, with Chat, Cowork, and Claude Code tabs), Grok Bot for chatting with xAI’s models, Hermes Desktop, OpenClaw, and the Perplexity desktop app.

Hermes Desktop is the one to know about, because there is only ever one Hermes on a machine. The app only runs against a runtime built from its own commit, so it installs one of its own under ~/.hermes on first launch, which takes a few minutes and shows its own progress. From then on that is the Hermes the terminal hermes command and the default agent use too, whichever order you installed them in. Installing it also hands Hermes the Omarchy theme as a skin named omarchy, which every Hermes surface follows as you switch themes; pick another under Hermes’ Appearance settings or with /skin if you’d rather it didn’t, and Omarchy leaves that choice alone. Removing the app under Remove > AI takes that runtime with it, and keeps your chats, memories, and the skills Hermes wrote for itself unless you tell it otherwise: it asks, defaulting to no, whether that data and your connection settings should go too.

OpenClaw’s desktop experience is its Control UI, which opens as a web app backed by its own local gateway. OpenClaw updates arrive through Omarchy’s package updates, so skip the Control UI’s own “Update Gateway” button: it would try to write into the package-managed install and fail. Removing OpenClaw under Remove > AI takes the gateway service and the app with it and then asks whether ~/.openclaw should go too, since that holds your chats and credentials alongside the plugin runtimes OpenClaw downloads for itself; the default keeps it.

Local LLMs

Omarchy recommends two ways of running local LLM models: LM Studio and Ollama. LM Studio provides a GUI interface for finding open-weight models, installing them, and running them. It’s a great way to get going easily. Ollama offers a CLI for doing so similarly. But if you’re new to local models, I’d start with LM Studio. You can install either under Install > AI in the Omarchy Menu.

The Omarchy Skill

Agent skills help AI use specific tools in a specific way, and Omarchy ships with a default skill for tailoring the system. Like tweaking your Hyprland config, adjusting the bar, or even creating a new theme from scratch. It’s symlinked into the skill directories for Claude Code (~/.claude/skills), Codex (~/.codex/skills), Pi (~/.pi/agent/skills), Antigravity (~/.gemini/config/skills), Hermes (~/.hermes/skills and each ~/.hermes/profiles/*/skills), and the generic ~/.agents/skills location, so most harnesses pick it up automatically.

But you should treat this skill as experimental. Different models will use it to different effect. It’s best to run in plan mode first, so you have an idea of what the agent would like to change. And then be ready to rollback changes or even invoking omarchy reinstall configs, if the agent makes a mess of everything.
